FIG. 2 is a front elevational view thereof;

FIG. 3 is a side elevational view thereof, the opposite side elevational view being identical thereto; and,

FIG. 4 is an enlarged fragmentary front view thereof.

The broken line showing of the tire sidewall and the innermost line outside of it to define the peripheral boundary of the tread in the drawings are for illustrative purposes only and form no part of the claimed design.
